manner and with freedom from mechanicaland operating defects during long perlods of tlme.

A more specific'object of the invention is .to provide a coin-pawl bypass whichwill sup plement the iusual gravity action of the coin positively toglift the pawl out of locking engagement'with a stop-upon operation of the} machine to vend an article, and which,upon the return operatiomwill again act positively to return the pawl to locking engagement Other objects oftheinvention will in part be obvious and ,will inpart appear hereinafter. The-invention accordingly comprises the features of-construction, combination o-f elements and arrangement of parts whlch will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the claims.

.30 For a fuller understanding of the nature and objects ofthe invention reference should be had tothefollowing detailed description taken in connection with the accompanying drawings, in which:

Figure 1 is a side elevational view of the device shown in normal positioninrelation to the coin chute; I I v Fig. 2 is a similar view of the device at the moment of approximate commencement of Fig' 3 is -a' fragmentary view of the device during the return operation} I j Fig. 1 is a fragmentary top plan View of the device; and f Figs. 5 and 6 are side and end elevations of the specific pawl-operating mechanism. v

Although the device may be usedin numerous connections, it is particularly adapted for usein connection with vending machines of the type describedand shown in United 1923. Seria1'No 286,560

;' 12, which is suitablypivoted on the frame of the machine as at '13 and has its forward end 14 normally in engagement with a stop11'5 of a cam 16f This cam is rotatably mounted upon a shaft 16, is adaptedto beoperated bya suitable lever" or the like 17, and is operatively connected to the vending mechanism of the machine (not shown).

As will be readily understood, the coinpawl 12 is so constructed and placed with respect to the pivot 13 that the forward end 14 normally rests in the position shown in Fig. 1, at which time operation of the machine is prevented. The gravity action of the pawl may, if desired, be supplemented by means of a coil-spring 18 attached to a pin 19 thereon and to the frame of the machine. Also, as is usual in a construction of such machines, the cam 16 is provided with a supplementary stop- 20 which. is somewhat higher thanthe stop 15 and acts to interceptthe pawl 14 if andwhen a coin ejector (not shown) removes an improper slug from the rear end 11. of the coin pawl.

or properslug is resting on the end 11 of the coin pawl, the forward end 14is raised to a When, however, as is shown in Fig. 2, a coin position of clearance with respect to the stop15 Y In order toinsure positive clearance of the stop 20 there is mounted upon the cam 16 a coin-pawl bypass 21 which is provided with Y a cam-portion 22, the forward end 22' of whichcnrves downwardly toward the stop 15, and the end 14: of'the coin-pawl 12 is equipped'with a projection or pin 23, which,

upon the forward or vending movement of the cam-and coin-pawl bypass, rides over the end 22of the cam-portion of thebypass. At this point the lever is checked by means of the coil spring 18 and while in this position is not sufficiently depressed to permit the coin to be discharged from the chute 10.

The coin-pawl bypass 21 is also provided at its rear end with an upwardly-extending cam-portion 22", over which, during the continued forward movement of the cam 16, rides the pin 23 of the coin-pawl 12. The spring 18 is thereby stretched further and the end 11 of the lever is depressed sufficiently to permit discharge of the coin. Since the portion 22 of the coin pawl by pass, in a preferred embodiment, is resilient in character, and the cam-portion 22" thereof projects somewhat higher than the supplementary stop 20, it will be depressed somewhat by the pin 23 during forward movement of the cam and, as shown in dotted lines in Fig.2, will snap upwardly after the pin 23 is passed.

Upon the return movement of the cam 16 the pin 23 is again positively engaged by the coin-pawl bypass 22, this time, however, by the under side 24 thereof, and upon continued return movement of the cam the pin 23 passes out under the end 22 thereof and is again forced into locking engagement with the stop 15 of the cam.

It will thus be seen that by the structure an unauthorized vending action of the machine is effectually prevented and it is impossible, even by rapid manipulation of the machine, to obtain a second vending operation with the same coin.

Since certain changes may be made in the above construction, and different embodiments of the invention could be made, without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted'as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which as a matter of language might be said to fall therebetween.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device of the type described, comprising, in combination, a movable cam having a pair of spaced stops, a gravity-controlled coin-pawl normally in engagement with one of said stops and adapted to be moved out of engagement therewith by the depositing of a coin thereon, a coin-pawl bypass associated with said cam and rearwardly of said firstmentioned stop, and means on the forward end of said coin-pawl for riding over said coin-pawl bypass positively to insure raising said coin-pawl out of engagement with the other of said stops during the vending movement of said cam.

2. A device of the type described, comprising, in combination, a movable cam having a pair of spaced stops, a gravity-controlled coin-pawl normally'in engagement with one of said stops and adapted to be moved out of engagement therewith by the depositing of a coin thereon, a coin-pawl bypass associated with said cam'and rear-' wardly of said first mentioned stop, and means on the forward end of said coin-pawl for coacting with said coin-pawl bypass positively to insure raising said coin-pawl out of engagement with the other of said stops during the vending movement of said cam; said last-mentioned means comprising a pin-member and said coin-pawl bypass having a forwardlyand downwardly-extending cam surface over which said pinmember rides upon movement of said cam.

3. A device of the type described, comprising, in combination, a movable cam having a pair of spaced stops, a gravity-controlled coin-pawl normally in engagement with one of said stops and adapted to be moved out of engagement therewith by the depositing of a coin thereon, a coin-pawl bypass associated with said cam and rearwardly of said first-mentioned stop, and means on the forward end of said coin-pawl for riding over said coin-pawl bypass positively to insure raising said coin-pawl out of engagementwith the other of said stops during the vending movement of said cam and positively to return said coin-pawl into engagement with both of said stops upon the return movement of said cam.
